Answer to Problem 10RE
The variables used in this work are as stream name, substitute, acidity, temperature and BCI.
Explanation of Solution
In the question, it is given that as a part of class work, a class at an upstate NY college collects data on the streams each year. Thus, the variables used in this work are as stream name, substitute, acidity, temperature and BCI. Thus, for the variables, the stream name is categorical as it is non-numeric, substitute is categorical as it is non-numeric, acidity is quantitative as it is measured in pH level, temperature is quantitative as it is numeric and BCI is also quantitative.
(b)
To find out what kind of graph might be used to display these data.

Answer to Problem 10RE
The graph suitable for these data is a pie chart.
Explanation of Solution
In the question, it is given that as a part of class work, a class at an upstate NY college collects data on the streams each year. Thus, the variables used in this work are as stream name, substitute, acidity, temperature and BCI. Thus, the kind of graph that will be suitable for these data is a pie chart as this data contains both categorical and quantitative variables thus, this graph will be helpful to display them more suitably.
